SPECIFICATION forming part of Letters Patent No. 320,166, dated June 16, 1885.

Application filed October 31, 1884.

To all whom it may concern:

Be it known that I, J OSEPH P. PARKHURST, a citizen of the United States, residing at Glens Falls, in the county of Warren and State of New York, have invented certain new and useful Improvements in Motors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, mak- Tc ing a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a side elevation of my improved motor-wheel, showing it connected to a shaft and located within a casing having a nozzle projecting into it to force the water or steam against the buckets of the wheel to give it a rotary motion; and Fig. 2 is a detail view in perspective of a portion of the motor-wheel, showing the peculiar construction of the buckets.

The object of the present invention is to provide a wheel with peculiarly-constructed buckets to be used as a motor, and operated by any suitable force brought in contact with said buckets, by which the wheel is given a rotary motion, which object I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the present instance, in order to illus- 0 trate the application of my invention, I have shown the wheel A as mounted on a shaft,a, and located within a suitable casing, B. Either through the side or top of the casing 13 projects a nozzle, 0, so formed upon its interior as to ejecta flat stream against the buckets D, to give to the wheel a rotary motion. I have shown water as being the force used in the present instance; but it is evident that any power may be substituted-such as steamal- 0 though water is preferable, as the principal feature of my invention is wholly in the peculiar construction of the buckets of the wheel. The buckets D are so constructed as to have their side walls, I), recede from their mouth 0, to form tapering sides to the interior of the buckets, and the outer wall, d, receding from a horizontal plane until it meets the apex of (No model.)

the angle formed by the angle of the two side walls, b, thus forming a tapering bucket in a horizontal and vertical direction, as shown in Fig. 2, the mouth of each bucket being of a width to correspond with the width of the stream projected from the nozzle 0. The object of the taper in the buckets is to have as small an opening therein as possible, causing less friction by its peculiar shape as it passes through the atmosphere, the tapering walls insuring the stream from the nozzle acting thereon with greater effect and increased power. It will be noticed that the buckets D are formed integral with and on one side of the body of the wheel, and are located a certain distance from each other, so that the stream from the nozzle will act on one bucket before entirely leaving the other.

Another feature of the invention is the angle which the mouth of one bucket has to that of the one preceding it, as shown in dotted lines, Fig. 1, the mouths of the buckets being at an acute angle with each other, and in front of each mouth is a deflecting-plate, e, to more effectually guide the stream to the bucket.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein shown and described waterwheel, the body of which has integrally formed therewith and onone side thereof rectangular-shaped buckets, the three projecting sides of which converge in straight lines to a focus, the fourth side being within the plane of the body, the buckets being relatively arranged to each other that a line drawn parallel and touching the outermost element of each bucket at every point will pass through the focus of the preceding bucket, substantially as and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOSEPH P. PARKHURST.
